Fix: Crash renaming modifier in Outliner and then toggling a property

If a modifier gets renamed elsewhere (through the UI in the Properties
Editor, python, ...) this ends up calling `rna_Modifier_name_update` --
which went fine because it does the neccessary depsgraph relations
update.

Doing the same from the Outliner missed that which then lead to crashes
in depsgraph modifier evaluation.

To resolve, add a case for `TSE_MODIFIER` in the Outliners
`namebutton_fn` that adds the required depsgraph relations update.

Also adds an appropriate notifier, so the name changes appear
immediately elsewhere in the UI.

Fixes #130536
